18650 3X2 Battery Pack

thingiverse

This is a 3X2 18650 battery pack. There are slots in the side to easily hook wires up if you'd like to balance charge the pack. I created this for my Bayangtoys X21 drone, to lay across the bottom leg supports. I figured running 3 18650's in series, with another 3 in parallel, I could get a much longer flight time. The top support beams are there to prevent accidental battery pop out. The + and - battery connector holes are slightly offset to give a little better cable management if needed. I printed this with everywhere support, in ABS. I wouldn't recommend PLA because if the batteries heat up enough, it'll deform the print. Depending on your metal battery connectors, you may need to elongate this to fit the cells. If you are using 18650's without the positive nub, you may need to shorten it a bit.
